The height of the antenna which is the distance from point A to point B is 4.5657 m.
What is Angle of Elevation?The angle of elevation is the angle created between the line of sight and the horizontal. The angle created is an angle of elevation if the line of sight is upward from the horizontal line.
Given:
We have to find two height h and H.
So, for distance H
H/ 27= tan 41
H= 27 x 0.8693
H = 23.4711 m
Now, for distance h
h/ 27 = tan 35
h= 27 x 0.7002
h= 18.9054
So, the height of the Antenna
= 23.4711- 18.9054
= 4.5657 m

Which equations represent circles that have a diameter of 12 units and a center that lies on the y-axis? Select two options. x2 + (y – 3)2 = 36 x2 + (y – 5)2 = 6 (x – 4)² + y² = 36 (x + 6)² + y² = 144 x2 + (y + 8)2 = 36
x^2 + (y – 3)^2 = 36
Step-by-step explanation:
The standard equation of a circle with center at (h, k) and radius r is
(x - h)^2 + (y - k)^2 = r^2.
If the center lies on the y-axis, then h = 0: (x - 0)^2 + (y - k)^2 = r^2
If the circle diameter is 12, then the circle radius is 6, and so r^2 = 36
So, among the given equations, your
x^2 + (y – 3)^2 = 36 is correct (but only if you use " ^ " for exponentiation).

9. The ratio of the measures of the three angles
10
in a triangle
is 10:3:7. Find the measure of the
largest angle.
Answer:
90 degrees
Step-by-step explanation:
10 + 3 + 7 = 20
10/20 x 180 = 90 degrees
Hope this helped :)
Answer:
The largest angle is 90 degree[10]
Step-by-step explanation:
Let 10:3:7 be x
10x+3x+7x = 180 [ angle sum property of a triangle ]
20x = 180
x=180/20
=9/1
=9
10x=10*9=90
3x=3*9=27
7x=7*9=63
90>63>27
therefore the largest angle is 90 degree.

Triangle PQR is transformed to triangle P′Q′R′. Triangle PQR has vertices P(8, 0), Q(6, 2), and R(−2, −4). Triangle P′Q′R′ has vertices P′(4, 0), Q′(3, 1), and R′(−1, −2).
Part B: Write the coordinates of triangle P′′Q′′R′′ obtained after P′Q′R′ is reflected about the y-axis. (4 points)
The coordinates of triangle P′′Q′′R′′ obtained after P′Q′R′ is reflected about the y-axis include the following:
P" = (-4, 0).
Q" = (-(3), 1) = (-3, 1).
R" = (1, -2).
What is a reflection?In Geometry, a reflection over the y-axis (y = x) is given by this transformation rule (x, y) → (-x, y). This ultimately implies that, a reflection over the y-axis would maintain the same y-coordinate while the sign of the x-coordinate changes from positive to negative or negative to positive.
By applying a reflection over the y-axis to the coordinates of triangle P′Q′R′, the coordinates of triangle P′′Q′′R′′ include the following:
(x, y) → (-x, y)
Coordinate P' = (4, 0) → Coordinate P" = (-(4), 0) = (-4, 0).
Coordinate Q' = (3, 1) → Coordinate Q" = (-(3), 1) = (-3, 1).
Coordinate R' = (-1, -2) → Coordinate R" = (-(-1), (-2)) = (1, -2).

In a triangle ABC, AB=AC. If D is the mid-point of the side BC, prove that:
i) AD is perpendicular to BC.
ii) AD bisects angle BAC
Answer:
Step-by-step explanation:
Given: In triangle ABC, AB = AC and D is the midpoint of BC.
To prove:
i) AD is perpendicular to BC.
We can prove this by using the midpoint theorem, which states that a line segment connecting the midpoints of two sides of a triangle is perpendicular to the third side and half as long as the third side.
Since D is the midpoint of BC, we have BD = DC. Thus, the line segment AD connects the midpoints of sides AB and AC of triangle ABC.
By the midpoint theorem, AD is perpendicular to BC and AD = BC / 2.
ii) AD bisects angle BAC
We can prove this by using the fact that if two line segments are perpendicular and one is an altitude of a triangle, then the two line segments divide the triangle into four smaller triangles that are congruent by SAS congruence.
Since AD is perpendicular to BC, we have two right triangles, ABD and ACD. By the Pythagorean theorem, we have AB = AC, which means that ABD and ACD are congruent by SAS congruence.
Since ABD and ACD are congruent, we have angle BAD = angle CAD. Also, since angle BAC is the sum of angles BAD and CAD, we have angle BAC = 2 * angle BAD.
Therefore, by substitution, we have angle BAC = 2 * angle CAD. This means that angle CAD is half of angle BAC, or in other words, AD bisects angle BAC.
Hence, we have proved that in triangle ABC, AD is perpendicular to BC and AD bisects angle BAC.

A small theater had 9 rows of 27 chairs each. Workers just removed 7 of these chairs. How many chairs are left?
Answer:
236
Step-by-step explanation:
number of chairs left = total chairs - 7 chairs
total chairs = 9 × 27
= 243
243 - 7
= 236
Answer: 236
Step-by-step explanation:
We have to figure out how many chairs there are in total so you will do 9*27. That is 243. If 7 were removed, you would do 243-7 which is 236. Therefore, there are 236 chairs left.
A 6 month loan has $5,000 in proceeds and a discount rate of 10%. Determine the face value
Answer:
the face value of the loan is $5,263.16.
Step-by-step explanation:
To determine the face value of the loan, we need to use the formula:
Face Value = Proceeds / (1 - Discount Rate * Time)
where "Time" is the time period of the loan in years.
Since the loan is for 6 months, we need to convert this time to years by dividing it by 12. Therefore, "Time" = 6/12 = 0.5 years.
Now, we can substitute the given values into the formula:
Face Value = 5,000 / (1 - 0.1 * 0.5)
Face Value = 5,000 / (1 - 0.05)
Face Value = 5,000 / 0.95
Face Value = $5,263.16 (rounded to the nearest cent)
Therefore, the face value of the loan is $5,263.16.

Explain about y-coordinate.The second component of an ordered pair is a y-coordinate. The y-coordinate denotes the directional separation of the point from the x-axis when an ordered pair is graphed as the coordinates of a point in the coordinate plane. The ordinate is another term for the y-coordinate.
According to question:We have,
y = x/2 - 4 and y = -2x + 1
Equate both equation
x/2 - 4 = -2x + 1
x - 8 = -4x + 2
5x = 10
x = 2

In ΔJKL, l = 920 inches, j = 880 inches, and ∠K=157°. Find the length of k, to the nearest inch.
In the triangle ΔJKL, the length of side k found using the law of cosines is approximately 1764 inches.
What is meant by the law of cosines?
The law of cosines, commonly referred to as the cosine formula or cosine rule, is a relation in trigonometry that links the lengths of a triangle's sides to the cosine of one of its angles. It claims that we can determine the length of the third side of a triangle if we know the length of the first two sides and the angle between them.
If ABC is a triangle, then as per the statement of cosine law, we have:
c = [tex]\sqrt{a^{2}+b^{2}-2 a b \cdot \cos \gamma}[/tex]
where,
c = length of side c
a = length of side a
b = length of side b
γ = angle opposite c
Given a triangle, ΔJKL
The length of side l= 920 inches
The length of side j = 880 inches
∠K = 157°
According to the law of cosines,
k² = l² + j² - 2.l.j . cos K
= 920² + 880² - 2 * 920 * 880 * cos (157°)
= 846400+ 774400 - (-1490481.46)
= 3111281.46
k = 1763.88 = 1764 inches.
